"The photo shown is a good application location for MANY protocols, especially when using essential oils for headache, anxiety and ADD/ADHD protocols. The suboccipital triangle is in close proximity to arterial blood flow to the brain and key neurological tissue." I've often tried to tell people in words where I used to apply oils for a migraine (I don't get them anymore) and it was hard to explain. This photo does a great job showing the location. by leannasuzanna
